At each site an area of about 1000 m² was defined, within which ten
1 m² quadrats were placed. On a single occasion, all the leaf litter
in each quadrat was collected and ants extracted using a Winkler bag. The
ants were pooled to form a single total for each site. From all sites and
samples, a grand total of 43,824 ants in 197 species and 47 genera were
recognised. All these are included in the Species list. Three species were
found only in the soil samples and 18 species were felt to be "tourists",
either being arboreal species foraging on the ground or Camponotus
species, which forage on the surface rather than within the leaf litter.

The "Prior knowledge" column is from my study of the
literature (the details can be seen in the related species pages on the
website).
